Last week police arrested Paul Dawson. They suspected him of being the leader of a gang of robbers who had been stealing art treasures from museums and homes since last January. Prior to his arrest, Dawson had spent two years in prison for theft. They had released him only 16 months ago. The police had been trying to find the gang's hideout for months. They feel sure they will arrest the rest of the gang by the end of the month.

- First, let's look at the verb "arrest". In the sentence, it says "Last week police (arrest) Paul Dawson.". Since "last week" is a specific time in the past, we use Past Indefinite for this verb. So, the correct form of the verb "arrest" would be "arrested".

- Next, let's focus on the verb "suspect". The sentence says "They (suspect) him of being the leader of a gang of robbers.". Since it is a general statement about a continuous situation, we use Present Perfect for this verb. Therefore, the correct form of the verb "suspect" would be "have suspected".

- Now let's move on to the verb "steal". The sentence says "who (steal) art treasures from museums and homes since last January.". Since it refers to an action that started in the past and is still continuing up to the present, we use Present Perfect for this verb. So, the correct form of the verb "steal" would be "have stolen".

- Let's analyze the verb "spend". The sentence says "Dawson (spend) two years in prison for theft.". The action of spending two years in prison happened before the time of the sentence, so we use Past Perfect for this verb. Therefore, the correct form of the verb "spend" would be "had spent".

- Now let's tackle the verb "release". The sentence says "They (release) him only 16 months ago.". Since it refers to an action that happened in the past, we use Past Indefinite for this verb. Hence, the correct form of the verb "release" would be "released".

- Moving on to the verb "try". The sentence says "The police (try) to find the gang's hideout for months.". The action of trying to find the gang's hideout is a continuous action that started in the past and is still ongoing. Therefore, we use Present Perfect for this verb. So, the correct form of the verb "try" would be "have been trying".

- Finally, let's look at the verb "arrest" again. The sentence says "They feel sure they (arrest) the rest of the gang by the end of the month.". Since it refers to a future action, we use Future Indefinite for this verb. Hence, the correct form of the verb "arrest" would be "will arrest".

So, putting it all together, the complete answer would be:

"Last week police arrested Paul Dawson. They have suspected him of being the leader of a gang of robbers who have stolen art treasures from museums and homes since last January. Prior to his arrest, Dawson had spent two years in prison for theft. They released him only 16 months ago. The police have been trying to find the gang's hideout for months. They feel sure they will arrest the rest of the gang by the end of the month."
